% \begin{theorem}
% There is no largest prime number. \end{theorem}
% \begin{enumerate}
% \item<1-| alert@1> Suppose $p$ were the largest prime number.
% \item<2-> Let $q$ be the product of the first $p$ numbers.
% \item<3-> Then $q+1$ is not divisible by any of them.
% \item<1-> But $q + 1$ is greater than $1$, thus divisible by some prime
% number not in the first $p$ numbers.
